2.4 Elements of an NC Block
An NC-block contains data for performing an operating step. The NC-
block consists of one or more words as well as the NC control com-
mands. The NC-block length must not exceed 240 characters, and it can
be split among no more than four lines.
An NC-block is comprised of the following elements:
•
NC-block number
•
Branch label
•
NC-words (NC control command(s))
•
Message
•
Remark in the program
•
Remark in the source program

CAUTION
All the elements of an NC-block except for function as-
signments must be separated by at least one space.

NC Block Numbers
N×××× × = 0..9
Each NC-block begins with the letter
N
followed by a 4-digit decimal inte-
ger number as the NC-block number. The numbering of NC-blocks in an
NC-program always starts at N0000. The numbering of NC-blocks is
automatically generated by the user interface when programming in 1-
step intervals.
When NC-blocks are inserted via the user interface, all subsequent NC-
blocks are automatically renumbered.
